SEPARATING OIL FROM FEED-WATER.

SPECIFICATION forming part of Letters Patent No. 386,114, dated July 17, 1888.

Application filed May Q11, i888.

To @ZZ whom, .it may concern:

Bc it known that I, DANIEL Do\'.t11Uu,aJ citizen of the United States, and a resident of New York, iu the county of New York and State of New York, haveinvented certain new and useful Improvements iu Apparatus for Separating Oil from Feed-W'ater for Oondensing-Engines, ol' which the following is a speciiieation.

Theinvention relates to improvements inapparatus for separating oil from Iced-water for condeusing-engines, and will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which- Figure 1 is a vertical section through an apparatus embodying the invention, the section being taken on the dotted line X X of Fig. 2, which is a front view of same, partly in section, on the dotted lineY Y of Fig. l. Fig. 3 is a back view, partly broken away, of same; and Fig. 4 is a sectional view taken on the dotted line Z Z of Fig. l.

In the drawings, A designates a box or reccptacle having plain sides and bottoni and an inclined top, l5, which is formed ol" a series of corrugations or elevations, C, and depressions l),as shown in Fig. 2. .Vithin the box or receptacle A are provided the inclined partitions E, which correspond in form with the top B and are parallel with the same and with eachother, cach of the partitions consisting of alternating elevations or domes F and depressions G, whereby between the partitions are formed spaces ll, extending in serpentine lines transverselyy across the receptacle. rlhe partitions E, any desired number ol' which may be used, are solid throughout,with the exception of an opening, I, provided in each one, the opening in each alternate partition being at one side ot" the receptacle and adjacent to the lower end of the spaces II, and the opening in the other partitions being` diagonally opposite to the inst-mentioned openings and located at the higher portion of the spaces II, as indicated in Fig. Ll. The alternating openings I are shown in Fig. 2, l'or the purpose ol' clearlyindieating by arrows the passage ofthe water downward through the spaces ll, the outlet-openings, which preferably should be at the upper end of the partitions, being in this instance, for clearness of illustration, shown at the lower Serial No. 2711,?393. (No model.)

end of thc partitions. In the lower portion of the receptacle is the water-space J,wherein are provided the vertical plates L, which extend upward into the deines F ot' the lower partition E, and cause the water, before escaping into the vertical pipe M, to pursue a serpentine course. rlhe pipe N, for supplying the water to the receptacle, is in connection with the usual hot well77 and enters the upper space, H, between the top B and upper partition E, as more clearly shown in Fig. 2. The outlet-pipe M connects with the usual pumps I'or supplying the boiler of the engine.

From the highest points of the serpentine spaces II and space J small pipes I lead to a tanlgQ, which islocatcd above the spaces IfI,but below the level ofthe water-line, which is denoted by a transverse dotted line in Figs. 1, 2, and 3. One pipe, l?, passes from each of the middle domes, O and F, and enters the bottoni ot' the tank Q, from which a pipe, t, having a valve, S, leads to the open air.

From the side deines C and F are brauch pipes T, leading to the pipes P, above mentioned, the branch pipes in the upper domes C F leading to the inner pipe I),those from the second row ot' domes Flcading to the second pipe l?, and those from the other domes F in succession leading tp the outer pipes l. From the high points ordomcs O ofthe upper space H air-pipes \V, having Valves c., pass to the air-pipe`R, as shown in Figs. l, 2, and 3. rlhc tank Q, is provided adjacent to its upper end with the dischargevalye b and connected by the pipe d with the reservoir c, containing a iloat-valve,f, (shown by dotted lines in Fig. 1,) and provided with a gage, g, and dischargevalve vlz.. rlShe reservoir c is connected with the condenser by the pipe t', having the valve j.

'In the operation el" the apparatus above described the water from the hot well is led through the pipe N into the upper space, H, (sec Fig. 2,) whence it passes diagonally across the upper partition E, as shown by solid arrows iu Fig. 4, to the opening l, through which it passes to the next lower space II and traverses the same in a diagonal direction, as indicated by the dotted arrows in Fig. 4, tothe opening l, leading to the next lower space H. The water traverses the partitions E in a diagonal direction. and in a serpentine course until it issues into the space J, whence it ascends over the first vertical plate L, thence downward and upward over the second vertical plate L, after which it is caused to iiow upward over the third vertical plate L, and finally enters the vertical pipe M, which, as aforesaid, is in connection with the pumps for 4supplying the feed-water t0 the boiler of the engine. The water entering the pipe N contains oil, and the purpose of the apparatus described is to cause the separation of this oil fromY the water prior to the latter entering the vertical pipe M, the vertical extension at the upper end of which opens to the air, While the horizontal branch of same leads to the pumps.

The operation of the apparatus may be successfully accomplished Without the aid of the reservoir e with its connections, although, if desired, the said reservoir may be made use of. During the passage of the water back and forth along the partitions E the air escapes through the pipes P, T, and V, and the pipes P and T will at first become filled with Water, which will rise into the tank Q and pipe R to the Water-level of the pipes N M. In the further operation the globules of oil in the Water will congregate in the highest points of the domes C and F and enter the pipes P and T, rising through the same to the tank Q. Each globule of oil will ascend through the pipes P and T and displace a corresponding quantity of Water, which will back into the spaces H. During the continued operation ofthe apparatus the water, which at first iilled the pipes P T, will be entirely displaced and the oil will grad ually accumulatein the high points of the domes O F and fill the tank'Q, which may then be emptied throughthe valve b, the water in the meantime flowinginto the pipe M, entirely free from the oil previously in it, and being in suitable condition for being supplied as feed-water to the boilers. When the reservoir e is made use of, the oil ascends through the pipes I and T, and, entering the tank Q, will ascend through the pipe d and enter the receiver e until the same has become filled, after which the oil may be discharged therefrom through the valve h. The vacuum in the condenser will aid in moving the oil upward into the reservoir e and in holding it there in suspension. The small valve suspended by the iloat at the top of pipe d will give Way at the pressure of the ascending oil, and the small valve supported by the iioat f at the lower end ot' pipe t' will prevent the full force of the vacuum from sucking the oil and water through the pipe i. As the reservoir e is gradually filling, the valve supported by the float will become more firmly held against the pipe i, so that as the oil approaches the pipe z the latter becomes more firmly closed against it and only a suflicient force of the vacuum is permitted in the reservoir to suspend the oil therein.

What I claim as myinvention, and desire to secure by Letters Patent, is-

1. The apparatus herein described, having the inlet supply-pipe and the delivery -pipe, combined with the receptacle having the series ot' partitions with alternating elevations and depressions, and pipes leading from the elevations to a tank for collecting the oil.

2. The receptacle having the partitions provided with alternating elevations and depressions and forming spaces H between them, combined with the supply -pipe, alternating openings I between the said spaces, the deliv ery-pipe, and the series of pipes leading from the higher points of the spaces to a tank, substantially as set forth.

3. The receptacle having the partitions provided with alternating elevations and depressions andalternatingopenings Leombined with the supplypipe, the delivery-pipe, the watercompartment J, plates L, and a series of pipes leading from the higher points of the spaces to a receiving-tank in communication with the air, substantially as set forth.

4. The receptacle having the supply and delivery and subdivided by partitions whose surfaces have elevations and depressions, and

openings I, combined with pipes leading from the said elevations to a receiver for oil con taining a iioat and being in connection with' May, A. D. 1888.
